A web roll cart for loading, unloading, and transporting rolls of web material wherein a handle may be pivoted between two different orientations, regardless of the presence of a roll of web material thereon. The two handle orientations permit the cart to be steered from either of two sides, and further permits a roll of web material to be presented to a web handling device in either of two orientations. A locking mechanism is provided so that the handle may be locked securely in either orientation while the cart is being steered. In a preferred embodiment, the web roll cart further includes four wheels, with two of the four wheels on casters for steering, and a v-shaped bed for receiving a roll of web material.
